Bipedalism is what drives “handedness”
Kangaroos are infamously left handed, and that may have to do with why they never developed language. That’s really the only thing stopping Tank Girl from becoming reality.
However so far no one has been approved for a grant to breed right handed kangaroos to see if they really do sound like Ice T.
But while a quadruped may favor one side or the other, it’s not the same.
I mean, it’s not really that easy there’d have to be some other changes.
But there is a pretty serious theory that if kangaroos had evolved to be right handed those other changes would have came about naturally until they eventually reached a state capable of advanced language.
Like, rather than the two hemispheres being connected the whole length, it’s only connected in the prefrontal cortex.
But if we never try to get talking kangaroos, it’ll never happen
Fuck AI or a robot butler, just get me a talking kangaroo buddy
